Filed: 1976-04-09
Abstract: 1501031 Differential gear EATON CORP 9 April 1976 [28 April 1975] 14507/76 Heading F2D In an automotive interaxle bevel differential gear a spider 48 is splined on an input shaft 18, one side wheel 38 is splined on an aligned output shaft 24 driving the rear axle, and the other side wheel 36 is freely mounted on the input shaft and splined at 50 to a housing 22, the hardened interior of which forms a part-spherical bearing for the differential pinions 40, whilst its periphery carries sprocket teeth receiving a chain driving the front axle. A slip-limiting friction clutch 44 connects the two side-wheels 36, 38, rather than, as is usual, one side-wheel and the input spider, whereby the torque requirement is reduced, and the sensitivity to slip increased. The housing 22 has a bolt-on extension 54 forming the outer member of the friction clutch 44, the inner member of which is formed by a part 64 having spring- loaded face-cam engagement with the sidewheel 38. Relative turning movement of the cam 64, to engage the slip limiting clutch 44, is produced by an acceleration-responsive inertia mass 68, pivoted at 72 on the housing 22 and in toothed engagement 66 with the cam 64 in such a manner, e.g. as described in Specification 1,436,856, which causes the mass to oscillate when differentiation is present. The rear part 16 of the casing forms a reservoir for oil, fed to the differential by a scroll 100 on the shaft 24, and a breather 82 is provided.

Abstract: 604,186. Spring couplings. TUSTIN, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 25, 1940, Nos. 14551 and 16099. [Class 80 (ii)] [Also in Group XXXVIII] In an electric follow-up system (see Group XXXVIII), anti-hunting components of control are produced with the aid of specially designed gearing between the control handle 50 and the electrical transmitting elements. The control handle 50 is carried by shaft 53 which drives generator 58 providing the velocity component and to which is secured one member 83 of a spring coupling, the other member 84 being secured to the shaft 62 of the variable resistance controller. The spring coupling comprises a disc 85 loosely mounted on shaft 53 and anchored to its hub a pair of spiral springs 86, 87, the free ends of which are bent radially and abut against pins 90, 91 on members 83, 84 and which operate in semicircular slots in disc 85. The springs are initially stressed so that the pins normally lie against diametrically opposite ends of the slots and the coupling is substantially solid until the torque applied to the handle overcomes that due to the springs which, thereafter, store the applied torque. The shaft 62 carries member 61 of the controller, the resistances being carried by a cage 66 the shaft 68 of which is coupled to the load. This controller is also described in Specification .577,312, [Group XXXVII], the spring coupling being described in Specification 577,489.

Filed: 1938-05-17
Abstract: 514,955. Colour photography, GASPAR, B. May 17, 1938, No. 14671. [Class 98 (ii)] A silver image is produced in an emulsion layer adjacent to an inactinic colloid layer uniformly dyed with a reducible dye resistant to ordinary photographic treating solutions and the dye is locally destroyed by treating both layers in a dye-destroying solution containing a catalyst. Dye-destroying solutions referred to are solutions of thiocarbamide and by hydrohalic acids and acid solutions of guanidine and its derivatives. Accelerating substances referred to are those described in Specification 490,451, a general formula being given. In an example, to a silver. halide emulsion layer on a support is applied a gelatin layer coloured yellow with Chrysophenine G or magenta with Tuchechtrot .3B, the dyes being precipitated with triph'enylguanidine acetate. The material may be exposed from either side, as the dye layer may be used as a filter, and after development and fixing, the dye is locally destroyed in a bath containing potassium bromide, sulphuric acid and 2À3- dimethylquinoxalline. The remaining silver is bleached and dissolved. A hydrochloric acid dye-destruction bath and a thiocarbamide dye-destruction bath containing also chromium alum, hydroquinone, sulphuric acid, and 2À3- dimethylquinoxal is referred to. Multilayer material containing several silver images and at least one separate coloured layer may be employed. Some of the image-layers may contain the dye for forming the image. In an example, on a support are coated (a) panchromatic layer, (b) a gelatin layer dyed with Tuchechtrot 3B (c) an optional uncoloured gelatin layer, and (d) an orthochromatic layer dyed with Chlorantinlichtgelb 5GL. This film is used as the rear film of a bipack of which the front film comprises a support carrying a blue sensitive silver halide emulsion layer and a gelatin layer dyed yellow with Chrysophenine G. After exposure, development and fixing the film is treated by the dye-destruction process. Specification 397,159 also is referred to.

Title: Improvements in devices for controlling the grinding head feed with automatic correction in a grinder where the grinding head feed is limited by a stop
IPC: B24B49/04
Filed: 1968-03-27
Abstract: 1,202,783. Grinding. SOC. NOUVELLE DE ROULEMENTS. 27 March, 1968 [13 June, 1967], No. 14672/68. Heading B3D. A device for controlling the grinding head feed in a grinder in which the grinding head feed is limited by a stop, said device having automatic dimensional correction, said grinder comprising an hydraulic actuator of the cylinder- and piston type for effecting the head movements comprises: (i) two movable wedge members having each an inclined plane of relatively moderate inclination, moving with the said grinding head and adapted themselves to move in directions substantially at right angles to each other, the first wedge member abutting at the end of the approach stroke of the grinding wheel against a fixed abutment of the frame structure of the machine, the other wedge member determining the end position of the first wedge member; and (ii) an electric device for detecting the position of said first wedge in relation to said second wedge member and controlling the fine-grinding and finishing operations to be carried out on the workpiece by controlling the relative position of said wedge members. A workpiece 1 is positioned on a support 2. A grinding wheel 3 is mounted on a head 5 having a cylinder 7 containing a fixed piston 6. Pressure fluid is supplied through valve 21 to the chamber 7a of cylinder 7, thus effecting rapid approach of the grinding wheel 3 until the inclined face 10 of a wedge 8 abuts a registering face on the machine frame 11. In this position, an exhaust port 36, supplied through a duct 37 and pipe line 38 with compressed air, is closed, actuating a pressure responsive switch 40, energizing coil 43 of a valve 44, whereby pressure fluid is supplied to the chamber 12a of a cylinder containing a piston 12 connected to the wedge 8 which is thus moved down to permit rough grinding, exhaust from the chamber 12b passing to the valve 44 through throttling diaphragms 55, 57 to determine the rate of feed. When a linear potentiometer 19 or other voltage divider signals a certain position, a coil 59 is energized, closing a valve 56 whereby exhaust takes place only through diaphragm 57 to give a slower feed for fine grinding. This is terminated when the wedge 8 engages a wedge 13; at this time, a signal from potentiometer 19 starts a time switch 61 to initiate a finishing period. At the end of this period, solenoid 23 of valve 21 is de-energized and pressure fluid is supplied to the chamber 7b of cylinder 7 to retract the head 5 rapidly. Port 36 is uncovered, opening switch 40, de-energizing coil 43 of valve 44, whereby pressure fluid is supplied through non-return valve 50 to chamber 12b to raise wedge 8 to its initial position. An instrument 64 measures the workpiece dimension and sends a signal to a stepping motor 16 which, through a screw and nut device 17, makes any necessary adjustment of the wedge 13.
